1/3 HP Submersible Sump Pumps Built To Handle Average Rain Storm

What Is The Pumping Performance Of A 1/3 HP Sump Pump?

A 1/3 HP sump pump can pump from 1,300 to 2640 gallons per hour at a ten foot vertical lift. The volume of water pumped is based on the power of the pump motor. Many manufacturers, including Wayne, Zoeller and Little Giant have built multiple 1/3 HP models with varying motor pumping capability.

What Is The Best Sump Pump Housing Material For 1/3 Horse Power?

The best sump pump housing material for a 1/3 HP sump pump is cast iron.
However, if the sump pump will not be used for pumping heavy rain storms frequently, a thermoplastic housed pump will do the job. An over-worked 1/3 HP thermoplastic horse sump pump will overheat quicker, trip the over load protection switch and the pump will cease to pump until the motor cools.

Thermoplastic housed sump pumps are more prone to warp and crack under heavy, continuous pumping. They are built to be discarded when they fail unless the housing is cast iron.

Cast iron housed sump pumps dissipate heat much better and are better suited for heavy, continuous pumping.
